Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00220 | $0.00220 |
| Opus 5.5 | $0.00088 | $0.00088 |
| Sonnet 5.5 | $0.00044 | $0.00044 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
flutter-intellij CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Additional Rules
- No I/O or heavy computation on the EDT (IntelliJ Threading Model).
- All
AnActionsubclasses must be stateless (no mutable instance fields). - Use
io.flutter.logging.PluginLogger(or IntelliJ'sLogger) for all logging; neverSystem.out. - All new source code files (
.java,.kt,.dart,.sh) must include the standard Chromium Authors copyright header. - Zero-Formatting Policy: do not comment on indentation, spacing, or brace placement.
- Categorize code suggestions with
[MUST-FIX],[CONCERN], or[NIT]severity prefixes. - Do not read, index, or search paths matching patterns defined in
.aiexclude.
Agent Skills & Workflows
- For standard project maintenance workflows and automated procedures (PR cleanup, verification fixes, unit testing, platform version removal, etc.), refer to the executable skills in
.agents/skills/.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
